    tracing, net, skb tracepoint: make skb tracepoint use the TRACE_EVENT() macro · 5cb3d1d9
    Zhaolei authored
    TRACE_EVENT is a more generic way to define a tracepoint.
    Doing so adds these new capabilities to this tracepoint:
    
      - zero-copy and per-cpu splice() tracing
      - binary tracing without printf overhead
      - structured logging records exposed under /debug/tracing/events
      - trace events embedded in function tracer output and other plugins
      - user-defined, per tracepoint filter expressions
